It is the object of my invention to provide an automatic control'device for maintaining at a constant level ,thetop of a pile, as `of lumber, from which boards or sheets are be- 5 ing removed, so that vas such boards or sheets are removed `the pile will be raised to keep its top substantially at a given level. In this way, as the boards or sheets arev taken from the pile, for instance to a planer or 1o other machine, the raising ofthe pile maintains the top of the pile always ata conven` ient level for the chine.

It is a further object of'my invention to provide such an automatic control device which can be thrown into and out of operative condition as desired; and whichV can be moved vto various positions and adjusted to various controlling levels as desired. It is a still further obj ect to provide a hand control device and asafety device which are associated with the automatic control device in a new way, to get certain interlocking controls between them.

I have illustrated my invention diagrammatically, to simplify the understanding thereof. The various devices conveniently illustrated maytake any suitable form, Vand may be varied in a number of ways; so that the drawing is illustrative merely.

The single ligure of the drawing isa. diagram illustrating my invention. Y '1 The platform 10 of a lumber-lift is shown as being raisable and lowerable by an electric motor 11, connected to the supporting stem 12 of the platform through any suitable gearing, including a rack and pinion in the illustrative form shown. The motor 11 is a reversib-le motor, sothat it raises or lowers the platform 10 according to the direction in which the motor rotates. The platform 10 is shown as being raisable and lowerable with operator to feed'the ma'- relation to a floor 13; and as being movable l said floor if such tracks are provided, to permit the trucki15 tobe rolled on to'and-off of the platform 12. Q

i The motorll is vshown as a three-phase al-` ARTHUR n. KRICK, or DANVILLE, INDIANA, Assrenonro THE nA'rroNA'r.

rections of rotation.: The switching means is shown as a single double-throwV switch, Vbe- 'causel that is perhaps the simplest way to obs.

. tain the' desiredaction of preventing thelclos-V ing of the circuit for both" directions ofn rotation of the motor 11 at once. f However, this illustrationris not intendedto limitthe switch to al single Vdouble-throw switch, as

4obvious variations are readily apparent.

'The switch2l has two operating solenoids 23 and' 24, for moving it to its opposite ezitreme positions-when such solenoids are ener. gized. VThe solenoids 23 and 24l aref'or producing upward and downward movement'respectively ofthe platform 10. The'switch 2l also hascentering springs v25 which tend tofmove it to vand hold it in its middle or open position, and do so when'thesolenoids'f 23 and 24 are both inactive.v

There are upper and lower limit switches 27 and 28,*provided in the circuits of vthe upward solenoid 23 and downward "solenoid `24'respectively for insuringthe de-energization of those solenoids when the platform v 30, and 31, for normally producing upward movement, downward movement, and stop'- pmg respectively. The .up and down pushbuttons 29 and 30are electricallyinter-` locked, by having not only theirfrontcontacts forproducing up and down movement y respectively, but by also having back contacts of which those of one push button (of all sets) must be connected `by Vthese pushbuttonsin order'for `the-circuit controlled bythe front contacts of'theother `of said push-buttons to be completed. Thatl is., in

orderl to close thelrupY circuit. through the solenoid 23 it is not only necessary that kthe vup push-button29 of a push-button set be depressedbut that the down pushbuttons 30'of'all sets'be not depressed; and

, in order to close the vdown circuit through only and the connections are such that these, stop push-buttons of all s-ets must-be 4undepressed in order for either the Yup-'cir-n cuit or the down circuit to be closed orto solenoid 23 or 24 which may be completed is the' solenoid 24 it is not'only necessary that the`down7 push-button 30 of a push-button set' be Ydepressed but that the Yupfpush-Y lbuttons'29- of all Asets bevnot depressed. The stopY push-'button 31 has back contacts remain closed; so that by the depressing of any stop, pu sh-button 31 the circuit of either only ifboth'the fdown7 push-buttons 30y and the rst'op push-.buttons 31ofall sets are not V depressed; it may be caused to move down'- '.wardrbydepressing any down push-button v Y Ying the'downward swing of the arm 43, and

30,' but only if both the uplpush-buttons 29 f andth'e sto push-buttons 31 otra-ll sets are not depressed.

Inaddition, the main switch 21A has-a sup- Y plemental 'or' holding `switch, 32, which `is swung into contact with the switch contacts `33 Yand 34 respectively upon the energiz'ation of the solenoids k23 and 24 respectively. hen either solenoid 23 and 24 is initially energized by thedepression of `an up or ,downpush`button 29 or 30 respectively, theV holding i switch 32 normallyA closes la circuit in shunt to said respective push-buttons,

V,through the'contactj33 or 34 respectively, for

lIrila-intaining the energization of the solenoid 23 or 24 after the associated push-button has ,beenlreleased; 'so that only kaV momentary depressiono the proper push-button'is necessary to produce upward orl downward movement of the platform. Such upwardor downward movement continues'until a stop push-button 31 is depressed, or until the proper limit'switch 27 or 28 is opened.

. (As so'far described, the mechanism is notl new; but the automatic `controlV now `to be described,` and the combination thereof with the other mechanism, are new so far as I.

'f course of lumber (now become'the top know.) Y f The `holding switch 32 may always be effective for the downsolenoid 24, untilthe .limit switch28 is opened or the stop push- '6/0 button 31 or up push button 29 is depressed but for the up solenoid 23`the holding switch 32 may be effective to maintain the circuit until the stop push-button 31 'or' the down 'bush-button 3() isdepressed, or the limit switch 27 is opened onlyY if `andgwhen the automatic control device is not in operative position, and is ineii'ective has a vertical post and which may beinoved to any convenient position so that it will not interfere withbut will be sufficiently close to the lumber 41 on the platform 10. vertically adjustable VVon the -postAk of Vthis stand is a block 42, on -which is pivotedy ak swinging arm 43 which may be swung down-l ward to thefull-lineposition orv up and back rto the dotted-line position, for making i the automatic control device opera-tive' and inoperative respectively.v

The swinging a-rm 43 carries two switches'Y 44 and 45, `which are spring-,pressed to open Y position and to closed position respectively'.

`The switch 44 is shown as a simple leaf'-A sprlng sw1tch;.which tends to spring Vopen and does so when the arm is raised to the Y dotted line position, butk which Vis pressed Ato closed position againstits-'cooperating contact 46 when the arm 43 is swung downward toits workingposition; For this, `the lock 42 carries a stop screwV 47 for limit'- a second switch-closing yscrew 48 ywhich engages theiswitch 44 and forces it againstthe contact 46 when lthe l arm ward. l

is swung down- They switchr 45 is shown as having a closingV spring 49 which tendstopress it against the two associated contacts 50 and 51. The switch yarm 45has a. pro-iectionfwhich `carries Aa roller 52, which the spring 49 tends to press away from the swinging arm43 to close the switch 45, but which when ,moved Vtoward thefarm 43 opens l such -switch-byg,

separatingthe armf45 from the contacts 50 andY 51. When the arm `43 is swung` downward, the rollerA 52 is placed over the pile of lumber.41; and the'rollei is moved upward to Yopen the associated switch 45 when V the top course of lumber israised to the desired level, and drops to close suchfa'ssoci# ated switch 45 when the top course of lum- ,ber is removed. Vith the arm 43 in its full.-

line or operative position, this movement of course) has'erisen sufficiently topraisethe roller 52 and open such switch 45.

The switch45 is connectedy in series in the i holding circuit for the up solenoid23, so that it must be closed in order that the hold-V ing circuit rmay be completed; vand vthe vswitch 44 is connected directly'across the 'holding switch for such up7 solenoid, or

between the holding-'switch arm 32 and the contact133, so that unless the switch 44V is ,ico

jllO4 open the opening and closing of the` holding switch on the vcontact Vproducesfno effectlxl In consequence, when the switch-arm4 43 is raised to its dotted line or inoperative poin sition, the switch 4-5 is closed and the switch 44 opened; so that the motor 11 and platform 10 are'controlled wholly/by the push afdown push-button to take control it is necessary depressed.

2. The limit switches 27 'and 28 remain effective as before.y A

3. Thefup push-buttons 27 becomeefthat all up push-buttons be' unfective only to `produce upward movement' of the platform 10 above the level set by the automatic control device and only so long as the push-button 29 is held depressed, (within the limit permittedby the up limit switch 27), but becomes ineffective to initiate Vupward movement which continues after the up push button is allowed to rise, and becomes ineffective to control the platform rise while the platform is below the level set jby the automatic control device since at that-time the platform isinoving upward under automatic control. Y

y 4. The holding switch `32 remains Veffective to control the holding circuit for lthe down solenoid 24; but becomes'ineffective` to control the holding circuitfor th'epup7 solenoid-23. v f;

Thus the swinging of the automatic-control arm 43 from operative to inoperative position, or vice versa, modifies the action of the manual control, and makes the control of the upward movement of the lplatform 10 primarily dependent upon ythe level of its top course of lumber. Y A,

This will be readily apparent from tracing the circuits; which tracing has'been deferred until after the description of`the general operation. I Y

The controlV circuits are shownconnected between the middle and left-hand leads of the main circuit 20. v i Y Starting at the middle lead, the current for downward operation passes by the wire to the solenoid 24, thence by the wire 61 toone contact of the down limit switch 28 thence by the wire 62 to one of the back contacts of one up push-button 29; thence in series through the back contacts of all the up push-buttons, and from the final back conthe swinging arm VV43.

'main circuit'20, the current for upward oper tact of theffup. pushbuttons by` the wire 63v 4to'fone of the front contacts of each down 'push-button 30.V If nowany such down7 push-'button is depressed, the current thenceV continues fromA the other front contact vof WO said down push-button 30 to the wire 64, and by it to one ofthe back contacts of one stop push-button 31 then in series through all the back contacts of the stopv :push-buti-l tons,.and from theiinal back Contact of the @i5 stop push-buttons 31^by the wire 65 to the leftfhand lead of the circuit' 20. Thus, if all gfup push-buttons and all stop push-buttons 31 are unedepressed, the depressingA of any down pushfbutton 30 closes the circuit "8`O forthe "down solenoid 24, which acts to swing the mainswitch 21and the holding -switch 22 to the right into Contact with their respective buttons. This closes the circuit for the motor 11',V in the proper direction to f cause it to lowertheplatform 10. The

- swinging of the switch arm 32 to the right closes a circuit inshunt'to the front contacts of the down push-buttons 30; so that the depressed down? push-button need not be 590 held, as if itis released the circuit closedby Y it is s till maintained through the switch 32in contact Vwith-the Abutton 34. This circuit is by-way of the wire 66 which leads from the wire 63 to the contact 34; and bya wire 67,(95 which leads lfrom the wire 64y to the switch arm 32. When the down circuit for the.V Y

motor 11 is thus closed, such motor continues in operation/to cause lowering of the .platformrlO until the circuit of the down solenoid 24 'is opened either bythe depression of Fico `an up push-button 29, thel depression of a stop7 push-button 31, or the automatic opening of the down limit switch 28. This control of the down movement isentirely inde? pendentfof'and unaffected by the'position -of` Again starting at the middle lead'of the ation passes by the wire 70 tothe solenoid 110 23, thence -by the wire 71 to one contact of Athe up limit switch 27; thence by thewire 72 to one ofthe back contacts of one down pushhbutton 30; thence in series through the back contactsof all the down push-buttons, "'115 and from the final back contact of the down7 push-buttons by the vwire 7 3 to one of the front contactsof each up push-button 29. If now any such up push-button is depressed, the current thence continues from the other front contact of said up push-button 29 to the wire 74,"and by it to J :the wire 64 andy to one of the back contacts of one stop 'push-button 31; then in series .through all the back contacts of the stop push-buttons, and fromthe final. back contact of thefstop push-buttons 31 bythe 'wire 65 as before to: the left-hand lead of the circuit 20. Thusiffall dowrfpushbuttons and all stop push-buttons 31 are unp-d'ejl `f'pireiss'ed,:the depressing-of any'iup push'- 'buttong29 closes theY circuit for the up sole'- ynoid 23, which4v actsto vswing the main switch w21 and the holding switch' 22 to the left into .contact with their respective buttons.. .This

closes the circuit -for the motor 11,V in the properdirectionto causeit to raise the plat- Y Vform 1Q. The'swinging of the-switchfarm 32 totheleft closes a circuit in shunt to the front contacts of the up.push'buttns 29, .provided the swinging arm 43 is in its upper or inoperativepositionyso that under those Acircumstances the depressed up`V push-butlton need not be held, as if it is released the circuit closed by it is still maintainedVA through the switchv 32 in: contact with lthe button 33. This circuit is by' way of thevwire "75.wh`ich .leads'from'the wire 73 to the contact 50, thence bythe switch arm 45 tothe contact 51, thence by the wire 7 6 tov the con# tactv33gp'andby the vwire 67, already referred to,"which leads from the wire 74 (as well as ffromthe wire 64)to the switch army 32.

hen the up circuit for'the motor 11 is thus closed, such'motor continues inpopera l tion, provided the. switch arm'43 is inraised f 'or-inoperative position, to cause raising of the platform 10 until the circuit of. theup solenoid is opened either by the depression of a down push-button 30, the depression Vof afstop push-button 31, or the automatic opening of the up limit switch 27. This control of the up movement is thus depend entupon the position of the swinging arm 43. In the vimmediately preceding paragraph, it is assumed that the swinging arm 43 is in its raised or inoperative position. If such -swinging'arm 43 is swung down to itsv fullline or operative position, vthe downward control remains thesame as before, under full control by the push buttons and down hold-Y ing circuit, yand the down push-buttons may supervene Vdand takecontrol fully `away from Y the automatic -control device. But the con` trol of the up movement/becomes different by theswinging down to operative Vposition of the arm'43. Primarily, such control isr made automatic, to cause raisin-g of the platform 10 whenever the top of the pile of lumber 41 isbelow a certain level, vand to stop such raising when the top of the pile of lumber reaches that level. The swinging down of the arm`43 closes the switch 44; and opens Vthe switch 45 if the top of the pile of lumber 41 is suiiciently high. If the top course of lumber is removed, the roller 52 drops, to close the switch 45; which closes the circuit `for the upsolenoid 23 through the parts 70, 23, 71, 27, 72, Aback contactsv of the down push-buttons 30, to which` point thecircuit. is the sameas alreadydescribed'; and thence by way ofthe wire 75, contact 50, switch 45, contact 51, wire 79, switch arm 44, contact '46",wire 80, rwirez67, wire 64,.backcontacts of the stop push-buttons 71, and wire'65 to the left-'handlead of the main circuit 20.

lumber pilest-rikes thefroller 52 and raises it to break the aforesaid circuit at the switch VIt still remains possible, .even under this automatic control, to produce at will downward movement of the platform v10 by depressing a down pushebutton=30g and to VThis starts' the motorllin operationg'and Vsuch operation continues until the top of the take away the automatic control entirely by n such depressionof such push button. Itis also still possible, as before, to stoprtheupward operation by depressing'a stop push button 31, but such stopping only continues while the stop7 pushfbutton is depressed if the top of the lumber pile is below the desired level, instead of. continuing. indefinitely 'as it does ifthe arm 43 is in its up .orinoperative position. Either of those operations breaks the control .circuit just above l described. Y

The downward movement` producedV depressing of a downpush-button 30, when onceinitiated even with; the swingingarm 43 v downward, continuesafter the releaseof the Vdepressed downll push button, because of the completion of the holding circuit by the wires (S6-.and 67 and the holding` switch 32 'Y A arm 43 in its operating position may be supplemented by the up push-button 29. By depressing suchy .up push-button 29,l the platform 10 may be made to travel upward independently of the roller 52 and switch 45 and at a point higher than theautomatic control would stop the'upward movement; but to do this it is necessary to hold the'push button 29 down for the full extent ofv thisfdesired additional upward movement, rbecause the holding circuitfor the up movement is then broken at the switch 45. This additional upward movement of the lumber pilemay be obtained without breakage, because theV additional rise-of the lumber pile, after it opens the switch 45 merely serves to'tilt the arm 43 Y upward about its pivot`.
